Please explain clearly relation among coefficient of coupling, voltage, turns ratio.

k1=turns ratio
k2=co-efficient of coupling
k1/k2=v1/v2
1/0.85=2/v2
v2=1.7v
k2=co-efficient of coupling
k1/k2=v1/v2
1/0.85=2/v2
v2=1.7v

What is the relation between coefficient of coupling and turn ratio?

v2 v1 = n2 n1.
v2/2 = 1 * 0.85.
v2 = 2 * 0.85.
Therefore v2 = 1.7.
v2/2 = 1 * 0.85.
v2 = 2 * 0.85.
Therefore v2 = 1.7.

No its 0.85 only. 85% of primary will link with secondary why?

k = n2/n1 = v2/v1.
0.85 = 1 = v2/2.
v2 = 2*0.85.
v2 = 1.7.
0.85 = 1 = v2/2.
v2 = 2*0.85.
v2 = 1.7.

Why transformer rating in kva not a kw?
